Universiti Putra Malaysia researcher to upgrade gamma cameras for 3D diagnosis

12.05.2014

The parts neatly laid out on the table are ready to be assembled to become a portable nuclear imaging diagnostic camera to detect breast cancer.

The difference of this prototype machine - the size of a large accordion - is that it uses angle-based gamma-ray detection instead of single angle-based detection to show up a tumour or cyst in 3D, so that doctors can zoom in for a sample for a biopsy, the gold standard test for any cancer.

The single-photon emission computed tomography (SPECT) camera device is the work of Associate Professor Iqbal Saripan, 33, head of the Department of Computer and Communication Systems Engineering in the Faculty of Engineering at Universiti Putra Malaysia (UPM). It has taken him more than seven years to reach this stage of his research and passion.

He said it all started when he was accepted for a place under UPM’s tutorship programme after graduating with his B.Eng (Hons) degree in Electrical-Electronics Engineering from Universiti Teknologi Malaysia in Skudai in 2001.

From here, he chose to go to the University of Surrey, United Kingdom, which is well-known for nuclear physics, where he pursued his PhD in medical image processing and completed his thesis on wire mesh collimator for gamma camera for his doctoral degree at age 26.

By then, he had not only gained some real hospital experience but had done a lot of groundwork to see how those multi-million ringgit nuclear imaging devices using 2D gamma-rays can be salvaged by switching to portable gamma-ray for pin-point diagnostic accuracy in 3D.

Like many other developing countries that employ these gamma rays machines, Malaysia has a few such machines for patients, each costing between RM5 million to RM10 million, and they are becoming obsolete.

The poser to the hospitals and government then is whether to replace these machines to those using the latest but expensive nuclear imaging devices or to put new changes to these gamma-rays cameras. The modification can be done by replacing their collimators to improve the performance of the current gamma rays.

In comparison, Dr Iqbal said that typical X-ray machines do not use such high blast of energy as gamma-ray and they cannot “see” through bones, like gamma rays.

But gamma rays can only pinpoint a tumour, or abnormal growth in the body, provided the body is injected with a weak and time-lapse radio isotope and the means where the gamma rays can be concentrated to produce the “image”.

This is where Dr Iqbal came up with his wire mesh collimator, a device that can improve the detection of gamma rays.

It took him years of research work and on-site studies and discussions with manufacturers, like Toshiba and Siemens, and medical doctors before he found the answers.

In the process, he filed one patent on the wire mesh collimators and was awarded a few national and international awards to his name.

He was given the Young Scientist award by Datuk Dr Ewon Ebin, the Minister of Science, Technology and Innovation, in November 2013, while the Academy of Sciences Malaysia recognised him a month later (in December) as one of the top Research Scientists in the country.

Dr Iqbal said he has received some foreign enquiries about his patents and is presently working on patenting another one of his work.

“I would say that 80 to 90 percent of my research work and publications are on nuclear imaging devices,” he said.

Right now, he and his team are ready to put together his prototype portable gamma-ray or SPECT camera for breast cancer detection.

The testing will be done at a hot lab facility in the country.

With inputs from his team of researchers, the portable SPECT camera can be used for young ladies and lactating mothers. “The camera can be used for breast of any volume,” he said with a grin.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
